                                  • Hi, when I'm doing a code clean up on a form class I'm getting the following error and the clean up doesn't happen.

                                    "One or more errors have occurred"

                                    By coping the class to notepad and coping in each method one at a time, I've narrowed it down to a certain method that is causing the problem.

                                    Then, by commenting out the lines in the method I've worked out which lines that is causing the problem. Once they are commented out the error goes away and the clean up happens.

                                    Basically all the commented grid lines cause the error.  To further narrow this down, I believe it's to do with the


                                    part of the code, however if I remove this the "Appearance" class is then ambiguous between and System.Win.Form

                                    I think this is the reason for the error, because if I change the USING at the top to "using XYZ = Infragistics.Win;" then change it in the code below to use XYZ, the clean up works, but I don't wan't to make those changes.

                                    Hope the below code helps you in solving the issue.


                                    private static void SetUpUltraGrid(UltraGrid grid) { //grid.DisplayLayout.Override.HeaderAppearance = new Infragistics.Win.Appearance() //{ // ThemedElementAlpha = Alpha.Opaque //}; grid.DisplayLayout.Override.HeaderStyle = HeaderStyle.XPThemed; grid.DisplayLayout.Override.ButtonStyle = UIElementButtonStyle.Office2007RibbonButton; //grid.DisplayLayout.Override.CellAppearance = new Infragistics.Win.Appearance() //{ // BorderColor = System.Drawing.Color.Transparent //}; grid.DisplayLayout.ScrollBarLook.ViewStyle = ScrollBarViewStyle.Outlook2007; grid.DisplayLayout.Override.MinRowHeight = 17; grid.DisplayLayout.ScrollBarLook.Appearance.ThemedElementAlpha = Alpha.Opaque; grid.DisplayLayout.ScrollBarLook.ViewStyle = ScrollBarViewStyle.Outlook2007; //grid.DisplayLayout.Override.RowAlternateAppearance = new Infragistics.Win.Appearance() //{ // BackColor = System.Drawing.Color.Transparent //}; //grid.DisplayLayout.Override.SummaryFooterAppearance = new Infragistics.Win.Appearance() //{ // BorderColor = System.Drawing.Color.Black //}; grid.DisplayLayout.Override.SummaryFooterCaptionVisible = DefaultableBoolean.False; //grid.DisplayLayout.Override.SummaryValueAppearance = new Infragistics.Win.Appearance() //{ // BackColor = Color.FromArgb(215, 215, 215), // BorderColor = Color.Black //}; var appearance = grid.DisplayLayout.Appearance; appearance.BackColor = SystemColors.Window; appearance.BackColor2 = Color.LightSteelBlue; appearance.BackColorDisabled = SystemColors.Window; appearance.BackGradientStyle = GradientStyle.None; appearance.BorderColor = Color.FromArgb(227, 239, 255); appearance.ForeColorDisabled = Color.SlateGray; appearance.ThemedElementAlpha = Alpha.Transparent; }

                                  Hi Alan,

                                  I spent some time trying to reproduce the issue but my attempts didn't succeed. Perhaps, the cause of the issue is related to specifics of your local environment. Would you please provide us with your CodeRush  and Visual Studio settings?

                                  1. Zip all content of the "%appdata%\CodeRush\Settings" folder and attach the archive to your next message.
                                  2. Click the Tools > Import and Export Settings menu item. Export all Visual Studio Settings and attach the obtained "*.vssettings" file to your next message.

                                  Also, please provide us with CodeRush logs obtained at the moment when the issue appears:

                                  1. Clear all contents of the following folder:
                                  2. Run Visual Studio and try to reproduce the issue.
                                  3. Zip all content of the Logs folder and send it to us.

                                  Sorry to hear you can't reproduce it. The issue is down to the lines that contain this:

                                  new Infragistics.Win.Appearance()
                                  I have noticed also that it's not just the "" but had it recently with other namespaces, but the end result would be an ambiguous error.

                                  I believe CRR is trying to move the "" part to the top as "using" ( I noticed this recently with System.Reflection), which will then give ambiguous errors on the "Appearance" class. I don't think any of the other addins I have does this move, only the CRR cleanup. However I've added all my VS Help About info below  as well as the requested files.

                                  The actual error in the CRR Package log is:

                                  Error: Message: Object reference not set to an instance of an object.
                                  Error: Type: System.NullReferenceException
                                  Error: Source: DevExpress.CodeAnalysis.CSharp
                                  Error: StackTrace:    at DevExpress.CodeAnalysis.CSharp.Refactorings.RemoveTypeQualifier.RemoveTypeQualifierRefactoring.ApplyRefactoring(RefactoringContext context)
                                     at DevExpress.CodeAnalysis.Refactorings.RefactoringAction.<Apply>d__4.MoveNext()

                                  It appears I can only attach one file, so have zipped up the VS settings and the log into the CRR zip

                                  Many thanks for the help:

                                  Hi Again

                                  Another quick update... Just been looking at my CRR settings and spotted a setting I have turned ON.

                                  In the Editor > C# > Code Clean Up

                                  Bottom option "Remove redundant type qualifies" this is turned ON... If I turn this OFF then the clean up works on with no issues, with it ON, I get the error mentioned .

                                  Hope this helps.

                                  Hi Alan,

                                  Thank you for the provided info. It was really helpful. Now I can reproduce the exception in simple code so we can fix it. Once we do it, we will update this thread. Please stay tuned.
                                  As a temporary workaround we would recommend you keep the "Remove redundant type qualifier" rule disabled.

                                  Hi Alex

                                  This is excellent news, glad you can reproduce the exception :)

                                  Now I know exactly what it is as well, when I get the exception I'll untick that rule and try again, that way if it's something else after unticking, I'll know :)
